Abstract

Profitability and productivity change over time are two key indicators to evaluate the performance of water companies. In this study, the profit inefficiency of water utilities was estimated based on the Luenberger Productivity Indicator (LPI). The empirical approach focused on the English and Welsh water industry from 2001 to 2018. It was illustrated that water companies suffered a profit inefficiency effect of 50%, mainly (44%) attributed to allocation inefficiency, whereas technical inefficiency contributed by 6%. Estimated profit LPI values revealed the impact of the price reviews on the profit productivity of the English and Welsh water companies.
